    <p>I have a java project that I can't quite seem to figure out right now. </p> <p>It wants us to create a composite object made up of 2D shapes from a package called Wheels. </p> <p>This composite object needs to take in <code>mouseEvent</code>s in order to move together when clicked and dragged on. I've already completed this part but the next part of the assignment requires us to have one part of that object to be independently drag-able such that when you drag it, the whole composite object does not move. </p> <p>Although when you drag the composite object, the independent object should move the same amount maintain position relative to the composite object.</p> <p>Here's the class that I think would need some working on.</p> <pre><code>public Character(Color _color1, Color _color2) { _indPart1 = new IndPart(); // head _charPart2 = new CharacterPart(this); // body _charPart3 = new CharacterPart(this); //left arm _charPart4 = new CharacterPart(this); //right arm this.setColor(_color1, _color2); _indPart1.setSize(50, 50); _charPart2.setSize(50, 100); _charPart3.setSize(75, 35); _charPart4.setSize(75, 35); } public void setLocation(int x, int y) { _x = x; _y = y; //_indPart1.setLocation((_x - _otherPointx) + (x - 300), (_y - _otherPointy) + (y - 250)); // head _indPart1.setLocation(x, y - 50); // head _charPart2.setLocation(x, y); //body _charPart3.setLocation(x + 51, y); // right arm _charPart4.setLocation(x - 76, y); // left arm } @Override public void mousePressed(MouseEvent e) { _prevPoint = e.getPoint(); } @Override public void mouseDragged(MouseEvent e) { _currPoint = e.getPoint(); //_otherPointx = _indPart1.getXLocation(); //_otherPointy = _indPart1.getYLocation(); _diffx = _currPoint.x - _prevPoint.x; _diffy = _currPoint.y - _prevPoint.y; this.setLocation(_x + _diffx, _y + _diffy); _prevPoint = _currPoint; //_otherPointx = _currPoint.x; //_otherPointy = _currPoint.y; } public void setColor(Color c1, Color c2) { _indPart1.setColor(c1); _charPart2.setColor(c2); _charPart3.setColor(c1); _charPart4.setColor(c1); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
